This invention relates to a heating and humidifying, and a cooling and dehumidifying device. The desirability and the healthful features of proper humidity in the air, are now 'generally recognized by physicians, Ventilating experts, and others. The atmosphere in living rooms, of course, is most deficient in humidity in the cooler months when the rooms are more or less closed and artificial heat is supplied. It is also now realized that it is very desirable to have a simple and efficient means for cooling the atmosphere of living rooms in the summer, when the weather is quite hot. It is also desirable at such times, to

reduce the humidity when the same is excessive,

so that the living rooms will be supplied with a fairly uniform degree oi humidity throughout the year.

It is an object of this invention, therefore. to'

provide a simple and eicient device which can be used to supply heat and humidity to living rooms in the months when heat is used, and can also be used to cool and dehumidify the atmosphere. of these rooms in hot weather.

It is a further object of the invention to provide a device comprising a plurality of members having spaced liquid receiving surfaces, means for heating or cooling said members, means for directing a viine spray of liquid over said members, la casing surrounding said members and means, and arranged so that air passes between said 'surfaces and through said spray, together with a. second set of members having spaced liquid receiving surfaces with means for heating and cooling said members arranged so that said air passes between said latter surfaces after passing' between the rst mentioned surfaces and through said spray.

It is still another object oi? the invention to provide a device asset forth in the' preceding 40 paragraph, in which a series of moisture eliminators are arranged between said first andlsecond mentioned lmembers.

It is another object of the invention to provide a devicesuch as set forth in the paragraph pre-A ceding-the last one, the same .having means for directing or forcing air upward through said casing and successively between the surfaces of 4said members. j i

0 These and other objects and advantages of the l invention wm be fnuy set fqrth 1n the fnunwing description made in connection with the accompanying drawings., in which like reference characters refer to similar parts throughout the several views and in which:- Y L Fig. 1 is a Vview in vertical section taken substantially on line I-I of Fig. 2;

Fig. 2 is a vertical section taken substantially on line 2 2 of Fig. 1; 1.

Fig. 3 is a partial view similar to Fig. 1 shown 5 on an enlarged scale; 1 j Fig. 4 isa wiring diagram of controls used with the device; and

Fig. 5 is a modified wiring diagram. l Referring to the drawings, a casing l0 is shown. 10 and while this'casing may be of various shapes, in the embodiment of the invention illustrated it is shown asI substantially. rectangular in longitdinal and transverse cross section. 'I'his casing may, of course, be ornamented as desired. Said -15 casing has a closed top and bottom and one end is shown as closed, while another end has an air inlet opening I 0a therethrough.` Casing I0 is shown as supported upon legs Illb arranged at the corners thereof. Within casing lIll adjacent 2 opening Ila is a ian casing il having therein a fan drivenv by a motor i2 mounted upon a base I3 which willbe suitably supported at the sides of Vcasing I0. Fan casing Il hasv an opening at its side' Ila. throughwhich air is taken in by the 25 fan in said casing, said air being discharged from said casing through a conduit I4 extending along the bottom of casing Il! and having a plurality of outlet openings Ha from which air issues, as indicated by the arrows in Fig. 1.Y Within the cas- 30 ing ill is another casing designated generally as l5. A radiator i6 is disposed in casing I0 at the lower .portion thereof, having header members I6a and lb between which extend the spaced 35 tubes IGc. Header member lia is shown 'as having a removable end plate |6e thereon secured by suitable bolts. This radiator is of the type shown as 23 in applicants co-pending application Serial No. 491,466, iiled October 27, 1930. 40 Tubes itc are shown as secured in the header members 'by coupling members I 6d. The tubes |6c extend through the casing I5, `'said casing having inclined end plates lia and |517 extending in parallel relation and between WhichfareA 45 disposed a plurality or series of members I1 hav ing liquid receiving surfaces, said 'members being illustrated as in the form of thin plates. The plates i1 are shown as arranged in parallel relation to each other and to the ends I 5a and 15b 50 andare supported upon the tubes I 8c, said tubes passing therethrough. These plates may be supported as are the plates 2l shown in applicants co-pending application above mentioned.

Casing l5 above and at the left of plates I1 as 55 ing its wide end vdirected toward the plates I1 shown in Fig. 1 is in the form of a cone I5c havand casing I5 has a semi-cylindrical top portion .I5d, as more clearly seen in Fig. 2, extending from the conical portion I5c. Casing I5 extends upwardly and has a pair-of parallelend walls I5e arranged in a zigzag plane and within which is slidably arranged a member I8. Member I8 comprises'end plates I8a and front and rear plates I8b and I8c respectively. vPlates I8a are supported on angles |51' secured to the sides of casing |51',

Betweenl the plates I 8b and I8c extend a plurality of zigzag plates ldand I8e, the same having portions'extending parallel to the end walls I8a. The plates I8e are disposed at the top of member I8 and have at their top edges the angular narrqw plates 9 which also extend between the iront and rear plates |81) and I8c. The plates I9-have their angles substantially bisected by the plates I8e. Plates I8a. have small plates at their upper ends parallel to one side of plates I9. The plates I8e have the lower portions I8f which have at their lower edges the narrow angular plates 20 `which extend between front and rear plates I8b and I8c and also have their. angles substantially bisected by the portions I8 f. It will be seen that plates I9 have their pointsf'or apices directed upwardly whilewthose of the plates 20 are directed downwardly. It will also be noted that the upperportion of plates I8e projects downwardly a short distance below and at the side of the tops oi?4 portions-.|812 The plates IFBd as shown in Fig. 1 are at the bottom of member I8 and have their lower edge portions I8i bent up- Ywardly at an angle of substantially 60,- these small upwardly bent portions |81' forming gutters at the bottoms of plates Id.. Plate I8a. at the like plates 2l having their apices directed upwardly and the angle thereof substantially 'bi-l sected by the portions I8g. Plate I8a at the right right of Fig. 1 has a small-plate at an angle thereto` similar to said latter portion, also forming a gutter. Plates I8d have upper portions IIlgI which have at their upper ends narrow angular troughas seen in Fig. 1l has a small plate alined with andl parallel tooneside of members 2|. The

portions I8g extend downwardly somewhat below the tops'fof the lower plates |811, thus forming an angle with said plates, and portions, I8g have their lower edge'portions |87 bent upwardly for a short distance substantially parallel to the low- 4at the bottoms of portions '|sg. -P1ate Isa at the Y er portions vof plates I8d, thus forming gutters left of member- I8 as seen in Fig, 1 has a similar gutter. 4It will be seen that the' portions I8g extend upwardly between the portions I8f. Gutterjportions I81,I8i, and 20 terminate a short distance from plate I 8c and over trough member 50. i Plate I8a has on itsiront a handle I8h.

Above the portions- I5e casing I5 has upwardly inclined end portions I5f and I5g parallel to each otherportions- I5g being extended "in the same plane by a portion I5h and an outletlcondzuit I5i 1 f extends from portions I5f and I5h and from the sides of casing I5, the same having an open end and extending-through one end of casing Ill,l said 'outlet portion I5z' being rectangular in ver-Q acens?? 23 having spaced liquid receiving surfaces are supported by tubes 22e, said members being shown as in the form of thin plates.` Plates 23 are shown as parallel to each other-and to the ends I5f and |59'A of the casing. .The radiators I6 and 22 are constructed and arranged to receive either a heating or cooling medium. -The radiator I6 is supplied through a conduit 24 controlled by asolenoid valve v25 under the control of a mercoid control ldevice 26. Tube 24 communicates with a supply pipe 21 which is connected to a supply pipe-28 which supplies cooling fluid and is controlled by the valve 29 as Well as with a supply pipe 30 which supplies heating iiuid and is controlled -by a valve3l. A'conduit 32 connects with conduit 21 'and supplies fluid to the header 22h of the radiator 22, this conduit being controlled by the magnetic valve 33 in turn operated or controlled by the mercoid control de- A .vice 34. A discharge or return pipe 35 leads from theheader I6a of radiator I6 to a common return pipe 36, and another vreturn pipe 31 leads from the header22a of radiator 22 and is connected to pipe 36. Pipe 36 is connected to a return pipe 38 which is the return pipe for heating iiuid and is controlled by the valve 39, and pipe 36 also is connected to the return pipe 40 which is the return pipe for cooling iiuid and is controlled bythe valve 4I.

Water under pressure is supplied roma suitable source through a pipe 42 having a manually operable valve 42a therein, said pipe 42 being shown as passing into the header I6a and then passing through one of the tubes I6c. Said` pipe is of sinuous form in saidtube so as to provide for expansion and. contraction. Pipe 42 extends through the header I6b and then passes into a strainer member 43. From the strainer 43 a tube 44 extends to amagnetically operated valve 45 from which a tube 46 extends, the same pro- Ajecting in to the end of conical portion I5c of casing I5 and terminating in a spraydischarge nozzle 41. .A trough 48 is disposed. below the plates I1, the same having transverse trough portions 48a and longitudinally extending troughs 4817I at its sides, said latter troughs discharging into an end trough 48o sloping toward its center and having -a discharge pipe 49 leadingthere from which extends downwardly through the bottom ofcasing I0. Trough 48 is substantiallyv the sameln structure as is trough 3l shown in applicants pending application above mentioned, and

saidtrough has openings or slots between thetransverse troughs 48a as -shown in Fig. 3.v A

discharge trough or gutter 56 is also provided below the member I8 and particularly below the lower members I8a`. adapted to receive from the troughs formed on the lower edges of plates Id,

and from thetroughs formed on portions I8g and I 8f. Drain pipe 50a leads from one end of trough 50 through the casing I5 toany desired point. f

In Fig. 4 a wiring diag-ram for the apparatus is shown, which includes the line conductors 5I and 52 which will be controlled by the main switch 53 preferably of the Square D type. A thermostat 54 will be disposed in the r'ooms to be heated, and this is connected to line conductor 5I rand to a contactor device or control device 55 comprising low and high contacts 55a and 55h respectively and' adapted to respectively control and close a pair of circuits. Device 55 has an operating magnet 55e. Thermostat 54 is connected to the line conductor 5I by a conductor 56 and is condevice` 11 is used, having lowand high contacts,

2,085,377 .nected to the contactor device by a conductor 51. Ahumidostat 58 is used, which is also connected to line conductor 5| by a conductor 59v and is connected by a conductor 60 to the solenoid valve control member l45 which controls nozzle 41. The mem-ber 45 is connected by a conductor 6| to another conductor 62 which in turn is connected to the'middle contact of a two-way switch 63. The switch 63 has a contact 63a connected by a conductor 64 to what is called the low contact 55a of the contactor device 55. Contact 55al -control device 34 which controls the valve 33.

The device 34 is connected by conductor 1I to the conductor 62 and hence to the switch 63 and to contacter member 55. Line conductor 5|. is so connected by conductor 12 to a control member or switch 13 for the motor. I2 and member 13 is connected by conductor 14 to theconductor 62. Line conductor 5| is connected to or extendsto another control device 26 which controls the valve and member 26 is also connected to conductor 62.'

In Fig. 5 a form of wiring diagram is shown, in which a three-contact thermostat 15 is used in `place of the thermostat 54 shown in Fig. 4.v With this 'thermostat a contactor member or control 11a and 11b respectively adapted to be connected by the movable member 11d. A conductor 16 connects the low contact 11a to the low contact oi thermostat 15. A conductor 16 connects the common wire of thermostat 15 to a contact on contactor 11 and a conductor 19 connects the high contact ofthermnstat 15 to a contact on contactor 11 and extends through a coil 11h. thereonf to the operating magnet coil 11o which actuates movable member 11d. v Another conductor 11g extends from magnet coil 111e to a coil 11f, and conductor 11e extends from coil 11f to high contact 11b.

In operation, when the rooms are to be heated, heating medium such as hot water or steam will be suppliedto pipe 3l) andvalve 3l will be opened'.

Valve 29 at this time will be closed. When the temperature drops below a certain point, assuming the diagram vin Fig. 4 is used, thermostat 54 will operate mercoid control 26 and valve 25 will be opened to permit heating medium to pass into I radiator I 6. This radiator, including the tubes -|60, will be heated and plates I1 will also be heated. l Motor I2 will simultaneously be started by thermostat 54 and fan II will deliver a 'current of air upwardly in the'casing I 5, which air passes through the openings in trough 48 between'the plates I1 and upwardly into the portion of the casing above said plates. When the humidity drops below a certain point, humidostat 58 will operate through the control valve so that uid under pressure will be admitted to pipe 46 and nozzle 41. However, valve 45 cannot be operated unless mercoid ated.

Referring to the diagram in Fig. 4, when thermostat 54 operates upon the temperature dropcontrol' 26 has already been operping to a certain point, conductors 56 and 51 will fbe connected atthe thermostat and current will 'of casing I5.

ow through the magnet 55e of contactor or control device 55. This can be traced from line conductor 5| throughconductors 56, thermostat 54, conductor 51 and magnet 55C, and thence to line conductor 52. The contactor now operates to close the contacts 55h and current flows from the hot side of line 52 through conductors 65, 61, contacts 55, conductor 66 to contact 63h oi switch 63, to the central contact of said switch, thence to conductor 62 from control members 12 'and 26 and to the other line conductor 5I, the

current passing from member 13 to line conductor 5| through conductor 12. It will be seen that after humidostat 58 operates' to close a connection between conductors 59 and 66, that current can then flow through member 45 by way of conductor 6| and conductors 60 and 59 to conductor 5|. It will also-be seen that unless thermostat 54 has operated to put current on conductor 62,l that humidostat 58 will not be able to be sprayed. by nozzle 41 unless there is heat in the radiator I6.

Water being admitted to nozzle 41, the same is |5d of casing This spray is encountered 'in casing I5 and through member. |8`. The air must pass between the plates |8e and I8d and will encounter the small angular plates I9, 20 and 2|. Should there be any fine drops or globules of water carried along in the air, .they will strike the plates I8d and |8e as well as the angular bafile plates I9, 20, and 2|, and will be precipitated on said plates and thus removed or eliminated from the air. The moisture thus eliminated will gather on the plates |8d and |8e and collect in the gutters formed in the bottoms of these plates, said moisture then drainingl downward into the trough 50. It will be noted, as clearly shown in Fig. 2, that the plates |8d and |8e, as well as the plates I9, 20, and 2| slope toward one side Some of the spray delivered by nozzle 41 may drop onto the plates |1 and will be distributed on said plates in a lm. As the air passes over these plates, the moisture will bev evaporatedby the air and heat of the plates, and

this moisture will also be carried along by the operate controlv member 45. Water cannot thus draininto vthe transverse troughs- 48a from -the lower edges of the plates and will pass through troughs 48h to trough 48o and.outthrough drain pipe 49.

Thermostat 68 will also operate and will act to actuate control member 34. Referring to Fig. 4, it will be seen that with current on conductor 62, this current can pass through' conductor 1I,'

member 34, conductor 10, thermostat 68 and conductor 69 to the line conductor 5T. Thermostat 68 may be set to operate at the same temperature as the thermostat 54, but preferably will be set to operate at a higher point. When control member 34 operates, valve 33 is opened and heating fluid will beA delivered to radiator 22. Tubes 22e and plates 23 Awill thus be heated.k

The air passing through member I8 then passesv between plates 23 and around thetubes 22e. This air is thus heated to a greaterdegree and this will evaporate any moisture that may yet be bodily carried along with the air. and will relatively `reduce the humidity carried in the airso that it is further from the saturation point. The

heated air with the evaporated moisture therein thus passes out of the discharge member Ilii and into the rooms to be conditioned. The air thus passes from casing I5 well charged with humidity, and the air in the rooms to be conditioned will thus have the desired degree of humidity.

As stated, member I8 is slidable and this m'ember can be moved transversely from'casing I5. The member I8 can be drawn laterally from casing I5 by. pulling outwardly on the handle I8h.

Whenv the wiring scheme shown in Fig. 5 is used with contactor 11 and thermostat 15 therlmostat 15 moves to connect conductors 16 and 18 when the temperature drops to a certain point and moves to connect conductors 18 and 19 when the temperature rises to a certain point.

When the temperature drops and conductorsv 16 and 18 are connected, current ows from the live side of line 52 to contact 11a, thence through conductor 16 to thermostat 15 and back on the common wire 18 which extends to a contact on contactor 11 and passes throughmagnet coil 11c and through conductor 80 to line conductor 5I.

' Magnet coil 11e operates and contact 11a and 11b and thence through conductor 80 to line conductor 5I. The member 11d will thus be held in place even if thermostat 15 moves to separate conductors 16 and 18. With current on conductor 8|, it will be seen thatl humidostat/58 can operate to actuate control member and deliver spray L to nozzle 41, current passing from conductor 8| through conductor 82, member 45, conductor 60,

humidostat 58 and conductor 59 to line conductor 5I. W'hen the temperature rises to the desired point, thermostat 15 will move to connectconductors 18 and 19 and current will flow from the livel side of line 52 through member 11d,`

conductor 11e, conductor 11g,ithrough conductor l18, thermostat 15,- conductor 19 and back through coil 11h of contactor 11 and through oonductor to line conductor 5|. The magnet 11e is thus short circuited and movable `member 11d will move away from contacts 11a and 11b and current will be cut off from conductor 8|.

Control device 13 will then act to-stop motor I2 l and controldevice 26 will act to close valve 25. It will be seen that while the current is on conductor 8|, that thermostat 68 can operate to actuate control member. 34 and open valve' 33 so that heat is delivered to radiator 22.

In hot weather the device can be used to.

cool and. dehumidify thkerair in the rooms. At

this time valve3l will be"`closed and` cooling medium will be supplied through pipe 28, valve 29 being open. It may be stated that when the device is to b'e used as a heating and humidifying apparatus, switch 63 willbe thrown so' that the central contact and contact 63h are connected. When the apparatus isbeing y ed .as acooling and dehumldlfylng apparatus, s itch s3 win be in position with the central contact and contact 63a connected. Under 'these conditions, whenv the Y temperature rises toal certain point in the rooms, the thermostat 54 will act as before described to place current on' conductor` 62 and control device 13 and 26 will be operated. At this time the current will pass from conductor 65 to contacts 55a and through conductor 64 to contact 63a.v of switch 63 and thence to conductor 62. y

Valve 25 will be opened, and the cooling medium will be supplied to radiator I6 so that this radiator, including tubes I6c, will be refrigerated or brought to a low temperature. Plates I1 will also thus be cooled. If the humidity rises to a certain point, humidostat 58 will, through control valve 45, operate to deliver liquid to the spray nozzle 41 and this spray will be directed in casing I5 as already described. It will be noted that humidostat 58 will not be able to act to have spray delivered at nozzle 41 unless controls plates I1 and around the radiator tubes |60 and A will be brought to a low temperature. and the humidity therein be reduced. AThe capacity of the air for absorbing moisture will, of course,

be reduced and the air will pass upward through the spray and through the member I8. Member I8 will act as already described to eliminate any drops or small globules of moisture which might bev inthe air. The air is now well cooled and after passing member I8, is further cooled by passing between plates- 23. As already described, after current'is on conductor 62, thermostat 68 lcan act to actuate the control' device 34 `and open valve 33' so that cooling medium will be supplied to radiator 22. Thermostat 68 preferably is set to act at a slightly lower temperature than thermostat 54. The air passingbetween plates 23 and around tubes 20c will be further cooled and its capacity to hold moisture thus further reduced. through outlet I5i after passing between plates 23 and passes to the rooms to be conditioned. A cool and dehumidied air, with the humidity at the desired point, is thus discharged into therooms. It, of course, is not desired to direct very cool air into the rooms, but the air will be desirably between 65 and 70 degrees Fahrenheit, and will have the desired degree of humidity.

Cool air; is delivered The same action will be had with the wiring r diagram shown in Fig. 5, the contactor 11 being actuated when the temperature rises to a certain point and the apparatus being rendered inoperative when the temperature drops to a certain point.

From the above description it is seen that ,applicant-has provided a simple and eicient heating and humidifying, as well as a cooling and dehumidifying apparatus. 'I'he device acts -to condition the air in the rooms and to insure a sumcient degree of humidity without having any excess humidity. The liquid delivered for the humidity is of small quantityand only slightly, if any, in excess of thaty actually required for the desired degree of.humidity.

'Ihe devie' is simple in construction and com-` pact and can be confined in a cabinet of comparatively small size which can be inconspicuously placed in a room. The device is accurate; A'

ly controlled and functions automatically. As above described, a desirable and comfortable temperature is maintained in both'summer and winter and a practically uniform degree of vhumidity is maintained throughout the year. It

is apparent that the device will have a high degree of utility for` the purpose intended. It will. of course, be understood that various .disclosed and defined in the appended claims.
